How does sulphuric acid reacts with sodium bromide?

NaBr NaBr + H2SO4 → NaHSO4 + HBr Not redox 2HBr + H2SO4 → Br2 + SO2 + 2H2O Redox The bromide ion in hydrogen bromide is a better reducing agent than chloride ions and reduces the oxidation number of sulfur in sulfuric acid from +6 to +4 in SO2.

What is the reaction between sodium chloride and sulphuric acid?

Sulphuric acid reacts with sodium chloride in the following way:2NaCl + H2SO4 → 2HCl + Na2SO4.

What happen when sodium react with sulphuric acid?

When sodium hydroxide react with sulphuric acid they form Sodium sulphate and water. The reactants involved in the process are sodium hydroxide and sulfuric acid. The reactants is base and an acid, which leads to neutralization process and yields a salt .

Which statement is correct about the reaction between concentrated sulfuric acid and sodium bromide?

Which statement is correct about the reaction between concentrated sulfuric acid and solid sodium bromide. Sulfuric acid acts as an oxidising agent. Which compound is used to treat the symptoms of indigestion? Which element has the highest first ionisation energy?

What happens when sodium bromide is heated with concentrated sulphuric acid?

In case of NaBr, Br- acts as reducing agent fr H2SO4 and the sulphuric acid is reduced to sulphr ioxide by bromide ion which itself gets oxideised to give bromine free molecule. 2NaBr + 2H2SO4 –> NaHSO4 + Br2 + SO2 + 2H2O.

Which observation is correct for reactions of HBr?

HBr(aq), forms two ions in solution. Which observation is correct for reactions of HBr(aq)? It effervesces addition of sodium carbonate solution. It forms a white precipitate on addition of silver nitrate solution.

What happen when sodium chloride reacts with sulphuric acid write balanced chemical equation also?

2NaCl+H2​SO4​→2Na2​SO4​+2HCl.

What happens when solid sodium chloride reacts with concentrated sulphuric acid also write chemical equation?

If we have solid sodium chloride and concentrated sulphuric acid then an acid/base reaction occurs. Steamy fumes of hydrogen choride gas are observed. The other product is sodium hydrogen sulphate NaHSO4 . This forms the basis of the laboratory preparation of hydrogen chloride gas.

What happens when sodium peroxide reacts with sulphuric acid?

sodium sulphate, hydrogen and oxygen.

What is the reaction between sodium and hydrochloric acid?

Sodium metal reacts with hydrochloric acid to produce salt and hydrogen gas.

What is the change in the oxidation number of sulfur when concentrated sulfuric acid reacts with NAI?

Iodide ions with sulfuric acid For the same reason H in water appears as +2, though each atom is +1.) The sulfur has been reduced from an oxidation state of +6 to +4. The iodine has been oxidised from an oxidation state of -1 to 0.

What happens when sodium iodide is heated with conc sulphuric acid?

As we can see, sodium iodide reacts with sulphuric acid to give fumes of hydrogen iodide along with the major production of iodine due to which the color of the solution changes to red. In this case sulphuric acid is strong enough to oxidize the iodide ions.
